Heat-resistant concrete with liquid and water glassis widely used for the lining of thermal units and equipment. In this paper we present the results of studies on the preparation and study of the properties of the sodium silicate composite binder (SNCR) on the basis of quartzite Kulantyubinsky field for heat-resistant concrete. Refractoriness quartzite 1450-1500 ° C. According to RFA quartzite consists of α - quartz, in addition, the sample contains kaolinite Al2O3 ∙ 2SiO2 ∙ H2O. SNCR is prepared jointly grinding quartzite and solid sodium silicate, a ball mill, taken from ootnoshenii: 90:10, 85:15, 80:20 to surface area 2800-3000 cm 2/g. To determine the optimal composition of the binder were determined flexural and compressive strength of samples, cross members 16х4х4 see Hardening SNCR carried drying in 2-stage operation in the temperature range 100-200 оC. Found that the bending strength of SNCR is 1.6-2.6 MPa, compressive 17,0-32,3 MPa.Refractoriness of 1320-1390 °C. The process of phase formation during heat treatment optimum binder composition.Was found that at temperatures of 1200-1300 ° C in SNCR by quartzite than β - quartz formed vykotemperaturnaya modification quartz β - cristobalite, which increases the fire resistance of binder. Presence of cristobalite phase was also found with the mineralogical On-petrographic method as well. resulting binder can be used for acid-and heat-resistant refractory Producth with 1300 оC and more.
